SPECIFICATION' forming part of Letters Patent No. 714,207, dated November 25, 1902.

Application filed July 14l 1902. Serial No. 115,534. (No model.)

To all whom it may concern,.-

Beit known lthat I, FRED LIPS, a citizen of the United States, residing at Arlington Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Molders Flasks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improved fastening and hinging devices for melders flasks and similar articles; and its object is to provide means by which one member of the flask may be separably hinged to the other member, so that it may be lifted therefrom and maintained in a fixed lifted position and at the same time may be entirely removed when desired and by which the two members of the flask or similar article may be automatically locked in position when brought together. I accomplish this object as hereinafter specified and as illustrated in the drawings.

That which I regard as new will be set forth in the claims.

Referring to the drawings, Figure l is a top or plan view of the cope placed upon the drag. Fig. 2 is a section on line 2 2 of Fig. l. Fig. 3 is a section on line 3 3 of Fig. l. Fig. 4 is an enlarged detail, being an isometric view of one of the front locking devices. Fig. 5 is an enlarged detail, being a vertical section of the front locking-lever. Fig. 6 is a sectional view of part of the ilask shown in Fig. 2, showing the upper portion raised and held in an upright position; and Fig. 7 is an enlarged detail, being an isometric view of the rear locking and hinging mechanism.

In the drawings, 8 represen ts the lower part or drag of the flask, and 9 the upper part or cope. The drag 8 is provided uponV one side with the projecting lugs or ears 10. (Best shown in Figs. l and 3.) The outer ends of the projecting lugs lO are rounded into circular form and are provided with V-shaped notches 11. (Best shown in Figs. l and 3.) The cope or upper part of the flask is provided upon the corresponding side with lugs or ears 12, the lower part of each of which is rounded in the arc of a circle and provided with an edge to rest within the V-shaped slot l1 of the lugs 10. The centers of the circles on which the ends of the lugs 10 and the bottom surfaces of the lugs 12 are formed are on the line of the top surface of the drag projected, as is best shown in Fig. 3. The edges of the lugs l2, bearing in the V shaped grooves of the lugs l0, afford a bearing on which the parts turn when the cope is lifted to the position shown in Fig. 6 and form a part of the rear hinging mechanism of the flask. Upon the same side of the drag, which I will call the rear, are two other lugs 13, which project outwardly therefrom. Each of the lugs 13 is provided with a suitable slot at its rear end, in which is pivoted a lever 14. The levers 14 are each provided with a shoulder l5, which projects inward toward the flask above the lug 13, and the lever is provided at its lower end with a projection 16, which is adapted to bear against the rear surface of the lug 13 and limit the backward motion of the lever 14. Each of the levers 14 is provided with a slot 17, which extends through the lever 14 to receive and engage the parts hereinafter described. The upper end of the lever 14 is preferably provided with a beveled shoulder 1S for the purpose hereinafter described. Upon the rear side of the cope are provided projecting arms 19, the outer ends of which are adapted to rest within the slots 17in the levers 14 and to be engaged thereby. Upon each side of their ends the arms 19 are cut away, so as to provide rounded shoulders 20, as is best shown in Fig. '7. The lower part of the arms l9-is adapted to bear upon the upper surfaces of the shoulders or projections 15 for the purpose and in the manner hereinafter described. The ends of the arms 19 are beveled downward and inward in order to form a secure resting-surface for the ends of those arms when the upper part of the flask is lifted into the position shown in Fig. 6, as hereinafter described.

Upon the front side of the drag are ears 2l, which are provided with a suitable opening to receive guide-pins 22, which are mounted in lugs 23 on the front surface of the cope 9. 24 indicates lugs which project forward from the front surface of the drag 8 and are similar in shape to the lugs I3 upon the rear side of the drag. They are slotted at their forward ends to receive each a lever 25, which is pivoted in said slot. The levers 25 are provided with a downward-projecting portion 26a below the pivot thereof in order to form a IOC) stop to limit their outward movement, as is best shown in Fig. 3. The levers 25 are provided with an inward-projecting shoulder 26 above the pivotal point of said levers, which when the levers 25 are in position projects inward toward the flask. The levers 25 are also provided with slots 27. (Best shown in Figs. 4 and 5.) The slot 27 passes completely through said lever and has its upper portion beveled upward and inward, as is best shown in Fig. 5. The slot is of such size as to receive and engage forward projecting arms 28, secured to the front surface of the cope 9. These forward-projecting arms are cut away on each side, so as to form a projecting portion 29, which is beveled downward and outward and is of suitable size to enter into and engage the slot 27 of the lever 25. The upper ends of the levers 25 are beveled downward and inward in order that said levers may be certainly thrown backward in proper position when engaged by the arms 28 when the cope is being closed upon the drag, as hereinafter described, and the outer ends of the arms 28 are beveled upward and inward in order to assist in the throwing outward of the levers 25 when theA cope is being lifted from the drag, as hereinafter described.

When it is desired to put the two parts of the flask together, the ends of the arms 19 are insertedin the slots 17 of the levers 14 and the lugs 12 brought to bear upon the V-shaped grooves 11 of the lugs 10. If the part-s are then lifted into the position shown in Fig. 6, the top surface of the arms 19 will engage with the upper ends of the levers 14, the lower ends of said arms 19 resting within the slots 17 and bearing along their lower surfaces on the shoulders 15 and the levers 14. The levers 14 being prevented from going any farther back bythe stops 16, the parts will remain in this position as long as-it is desired. When it is desired to close the two parts together, the cope is swung downward upon the bearings 10 11 12.y As it descends the lower surfaces of the arms 19 come in contact with the upper surface of the shoulders 15 just before the flask closes in the position shown in Fig. 2, forcing said shoulders downward, and consequently rocking the levers 14 inward, causing the slot 17 to engage with the upper surface of the arms 19 and preventing a separation of the parts when brought together by vertical lifting of the same.` At the same time as the cope descends the front ends of the arms 28, as shown in dotted lines in Fig. 3, engage the beveled surfaces of the levers 25, which have been previously thrown back in order to free the parts, as hereinafter described, and insure the levers 25 being thrown back into the position shown in dotted lines in Fig. 3. As the cope descends still farther the forward ends 29 of the arms 28 enter the slots 27 of the levers 25, and asA the descent continues farther the lower surfaces of the arms 28 bear `upon the shoulders 26 of the levers 25, rockin solid lines in Fig. 3, whereby the parts will be locked together, the slots 27 of the levers 25 engaging the projecting ends 29 of the arms 28 in the position ,shown in Figs. 4 and 3. The two members of the flask are thus locked together and cannot be separated byvertical liftingand without disengaging the front locking devices.

When it is desired to rock the cope back upon the drag, either to entirely disengage them or to separate them, the front levers 25 are pulled backward by hand. The cope may then be turned backward upon the drag upon the bearings 10 11 12. As the movement continues the rounded shoulders 2O bear upon the inner surfacesof the lever 14 until when the parts are lifted into the position shown in Fig. 6 they will maintain that position, as hereinbefore described.

I have shown and described my invention as applied to molders liasks,and it is particularly adapted to this purpose. It is obvious, however, that the same devices for separably hinging and fastening might be used on other articles than melders asks, in which it was desired to separably hinge two parts together and secure them in position, and I therefore do not confine my invention to such flasks, except as hereinafter specifically claimed. It is also to be noticed that while I have described my invention as applied to melders flasks adapted to have one part separately hinged upon the other so as turn thereon my fastening devices might be used upon a fiask 4which was not so hinged, but in which the cope was designed to be lowered directly upon thedrag, in which case the bearings 10 and 12 might be omitted. In such case the levers 14 and 25 would be thrown backward to give clearance and the cope lowered directly upon the drag. The arms 19 and 28 as the cope is lowered would in such case contact, respectively, with the shoulders 15 and 26, throwing the respective levers into such position that the slots in said levers would engage the ends of the arms and lock-them firmly in position. I therefore do not confine my invention so far as it relates to said fastening devices to hinged flasks, except as specifically claimed.

That which I claim as my invention, and desire to secure ,by Letters Patent, is-

1. The combination with two separablyhinged members having bearings on which said members may pivot, of an arm projecting from the hinged side of one of said members, and a lever pivoted on the hinged side of the other member in register with said arm and provided with means to engage said arm and with a projecting shoulder adapted to be engaged by said arm when said members are closed one upon the other and throw said lever into engagement'with said arm, substantially as described.
